This is the Army’s new lightweight Soldier Protection System

The U.S. Army of the future needs the gear appropriate for tomorrow's conflicts — and that means armor. Not only will that that future Army be responsible for everything it does at current, it also needs to be prepared for the unknown — situations we can't foresee today. Who knows which country or actors will be the major threat of the coming days anyway?

The Army's solution is the Soldier Protection System, a modular, scaleable armor that is both lightweight and adaptable to future technology and threats.

Like former Secretary of Defense Donald Rumsfeld once infamously said, you go to war with the Army you have, not the Army you might wish you had. Now, the Army is prepping to go to war with the Army it wants to have. Each piece of the new armor system is designed so the wearing soldier can modify and scale it up (or down) depending on the nature of their mission on any given day.

At its most minimal, the system is a 2.8 pound vest that is capable of being worn under civilian clothing. Even at such a small weight, the new armor can still stop rounds from a sidearm. At its most protective, the armor is a mix of plates and soft kevlar that can stop blasts from explosions and shell fragments from munitions like Russian artillery shells — all without compromising the soldier's range of motion.

Over the course of the last 15 years of war, body armor has evolved — but usually only getting bigger and more restrictive in the process. The total weight of armor added to a soldier's carry topped out at 27 pounds in 2016. The Soldier Protection System, from its onset, has been aimed at curbing the weight, reducing it as much as one-quarter in some areas of protection. New systems also include hearing protection and a modular face shield, all without increasing the weight carried overall.

The old system was protective, but limiting in many ways. It had none of the included ear and eye protection the Soldier Protection System has and it was not very conducive to the terrain troops had to overcome in the mountains of Afghanistan. It also wasn't very helpful in beating the blazing heat of Iraqi deserts. The clunky armor was protective, but often impaired mobility while maneuvering and bringing small arms to bear while in the heat of the moment. When facing lightly-outfitted insurgents, and the armor could impede a soldier's ability when running to cover.

Even with the new modifications, the Army's armor doesn't protect much against the blast-induced brain injuries so common on the battlefields of the Global War on Terror. Even firing heavy weapons at an enemy can cause traumatic brain injuries. Some studies suggest the new, lighter-weight helmet of the Soldier Protection System can help with the issues surrounding blast damage, but cannot mitigate it completely.

The recent improvements in armor design aren't the end of the road for Army researchers. They continue to design and redesign the armor to meet the needs of today's (and tomorrow's) Army operations, to protect vulnerable areas not covered by even the Soldier Protection System while continuing to drop the total weight carried by U.S. troops in combat.
